IMPROVEM ENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 48,817, dated July 18,1865.

To alli'whom it 'may concern:

Be it known that I, C. M. JENNE, of Young America, in the county ofWarren and State of Illinois, have invented a new and ImprovedCultivator; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming part of this specication, in which- Figure lis a sidesectional view of my invention, taken in the line x Fig. 2; Fig. 2, aplan or top view of the same; Fig. 3, a front view of the same.

Similar letters ot reference indicate like parts.

This invention relates to a new and improved cnltivator for plowing orcultivating corn and other crops which are grown in hills or drills; andit consists in a novel construction and arrangement of parts, ashereinafter fully shown and described, whereby the plows may be adjustedlaterally and vertically with the greatest facility, and at the sametime a very strong and durable implement obtained for the purposespecified.

A represents the axle of the device, which is of V form, or inclineddownward from its center at bot-h sides, as shown clearly in Fig. 3.

, This axle is ofcast or wrought iron, has a wheel, B, at each end ofit, and the draft-pole G passing through its center loosely, so as toadmit of a certain degree of play ofthe axle on the draftpole. The axleis represented as being in one piece; but it may, if desired, be formedof two equal parts or pieces and connected to the draft-pole by jointsor hinges.

' D D represent two stay-rods, which project from the draft-pole C, onefrom each side, and pass through the axle A, said rods having spiralsprings a on them 'back of the axle. These stay-rods and springs serveto brace the axle and draft-pole, and at the same time admit of aforward and backward play or movement of the axle at either side of thedraft-pole.

To the rear end of the draft-pole a bar, E, is attached by a hinge orjoint, b, and this bar is sustained or held in proper position by a rod,F, which is attached to the back end ot' E and extends forward to aplateQG, on the draft-pole, the former being secured to the latterv by ascrew, a, which passes through an oblong slot in the plate into thedraft-pole. By this arrangement the bar E may be held or sustained in amore or less inclined position by adjusting the plate G farther forwardor backward on the draft-pole.

On the draft-pole, just in front of the axle A, there is placed astirrup, H, which is attached to a shaft, c, the ends of which arefitted and work in suitable bearings, d, on the draft-pole. To the lowerends of this stirrup bars I are attached by pivots e, and the outer endsof these bars are iitted on rodsf, the back ends of which are connectedby links g to the axle A, as shown clearly in Fig. 3. The whifdetreesare attached to the front ends of the rodsf, and it will be seen that bythis arrangement the bars I are allowed to yield or give with the axleA,and a simple and efticent draft-equalizer obtained.

J J are two plow-beams, the front ends of which are attached by metalplates h h to V- shaped bars K, the upper and lower ends of which areprovided with pivots or journals, which are fitted in the upper andlower ends of bars L L, the latter being secured tothe axle A by centralpivot-bolts, c'. By connecting the beams J with the axle A in thismanner a universal-joint connection is obtained, and the beams may beraised and lowered and moved vertically as required. The front ends ofthe beams J J have rods M fitted in them, the upper parts of which areconnected by links N with adjustable bars O O, attached to the draftpoleC. By adjusting these bars O farther inward or outward from thedraft-pole the beams J J may be secured at a greater or less distanceapart.

Each plow-beam has two standards, P P, at-

tached to it, the lower ends of which have shovelshares Q attached tothem, of the usual or any proper form, and to the upper end of eachinner standard, l), there is secured a hook, It.

These hooks, by raising the rear ends of the beams J J, are fitted onthe rod F, and the shares or plows Q are thereby held up above thesurface of the ground at a greater or less height, as may be desired, byadjusting the bar Ein a more or less inclined position by securing theplate G farther forward vor backward on the draft-pole.

By having the axle A arranged, as shown, so

that it will yield or give, the implement is prevented froin beingstrained or broken in case any of the plows meet with obstructions.

I claim as new and desire to secure by Letters Patent 1. The axleA,arrangcd or applied to the draft-pole C, substantially as shown, toadmit of a forward and backward play thereon, for

the purpose set forth.

2. In combination with the above, the rods D D, attached to thedraft-po1e C and passing through the axle A, with springs a ontheir rearends, to operate substantially as and for the purpose herein set forth.

3. The stirrup H, applied to the draft-pole C,

for the purpose specified.
